Specification of Letters Patent.

Patented Oct. 30, 1906.

Application filed December 5,1905. Serial No. 290,866.

To all whom it may concern;

Be it known that I, SAMUEL W. WHONN, a citizen of the United States, residing at Seattle, in the county of King and State of Washin ton, have invented certain new and useful mprovements in Extension-Tables; and I do hereby declare the followin to be a full, clear, and exact description 0 the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My inventionrelates to extension-tables; and its object is to provide a table with a sectional top the parts of which are adapted to move in opposite directions, said parts being connected in a novel they will be simultaneously moved by pu ing upon either section.

The invention also consists of certain other novel features of construction and combination of parts, which will be hereinafter more fully described, and pointed out in the claim.

.In the accompan ing drawings I have shown the preferred orm of my invention.

In said drawings, Figure 1 is a bottom plan view of the table. Fig. 2 is a central transverse section therethrough. Fig. 3 is a view similar to Fig. 1, but showing the table extended.

Referring to the figures by numerals of reference, 1- and 2 are the end and side strips, respectively, of the table-frame, and 3 represent brace-strips therefor. The heads 4 of table-legs 5 are adapted to be placed between the ends of the strips 1 and 2, forming a support for said frame.

Secured within the frame adjacent each side stri 2 are arallel guide-strips 8, having joinin beads 9 ormed ong'itudinally along their adjoining faces. Slides 10 and 11 are mounted between each pair of guides 8, and their adfaces contact, while their opposite faces ave longitudinally-extending grooves 12, into which the beads 9 project. The slides 10 and 11 maybe of any desired length, and they extend in o posite directions through the end strips 1 o the frame and are secured to the sections 13 and 14, respectively, of the table-top. Those portions of the slides which are mounted within the end manner, whereby end of the table-top strips 1 are of less thickness than the balance of the slides, so that stop-shoulders 15 are formed, which are adapted to abut a ainst the strips 1 and limit the extension of t e table. A cross-beam 16 connects the centers of the inner guide-strips 8, and a pin 17 extends downward from the center of this beam 16 and constitutes the fulcrum of similar crossed levers18. These levers are pivoted at their centers, while their ends are connected, by means of links 19, with the slides 10 and 11. One end of each lever is connected to one of the slides 11 of one pair b means of its link 19, while the other end 0 said lever is connected by its link to the slide 10 of the other pain It will therefore be obvious that should the section 13 of the table-to be moved lon itudinally its slides 10 wil operate both 0 the levers 18 and will cause said levers to impart a corresponding movement to the slides 11 and their table-to section 14. The extension or shortening o the table is thus greatly facilitated, because by pushing or pulling upon either a corresponding movement in the opposite direction will be imparted to the other end of said top.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In an extension-table, the combination with a suitably-supported rigid frame, guidestrips arranged in pairs, and a cross-beam connecting the centers of the inner guidestrips; of a pair of crossed levers fulcrumed to said cross-beam, op ositely-movable slides between each pair 0 tions secured to said op ositely-movable slides, links at each end 0 each lever, one link of each lever engaging one set of slides and the links at the opposite ends of said levers engaging the opposite movable slides whereby said top sections will move in unison from each other.

In testimony whereof I have signed my name to this specification in the presence of two subscribing wsitnesses.
